SunPass sticker tags ready for use in SunPass only lanes right away, but wait a day if you're driving through cash lanes or express lanes

Q: The SunPass Mini transponder is not ready in a matter of minutes, as Florida's Turnpike officials recently indicated in the Sun Sentinel. They are usually activated within 24 hours. I found that out after buying one and trying to use it four hours later.

A: According to the SunPass website, the sticker tags can be activated and used immediately in SunPass-only, E-Pass-only (in Orlando) and Leeway-only (in Fort Myers) lanes.

If you need to drive through mixed-use lanes that accept both SunPass and cash or the I-95 express lanes, you need to wait until 6 a.m. on the morning after you activated your transponder.

"Although the funds in the account may not show up immediately upon activation, the system will recognize the license plate number and deduct the toll from the account," said turnpike spokeswoman Sonyha Rodriguez-Miller.

Q: The traffic signal at Sunrise Boulevard and Andrews Avenue in Fort Lauderdale is extremely long if you're on Andrews. You can sit at the light for more than three minutes with no traffic on Sunrise. Can it be adjusted for early mornings on weekends?

Greg Webb, Fort Lauderdale

A: It's working properly now, but Broward County traffic engineers were challenged to come up with a solution.

At first, technicians cleaned the video detection cameras, but saw no improvement in the signal's operation. That spurred more tests and night-time observations, which led them to conclude that a nearby street light was interfering with the detection equipment.

Technicians adjusted the equipment to account for the street light and the signal is now working as it should.

Q: What's the statute on left turns on red between two one-way streets?

Tony Scalo, Lauderhill

A: A left turn on a red arrow from a one-way street onto another one-way street, after stopping, is allowed unless a sign prohibits turns on red.

The statute can be found under section 316.075 for Traffic Control Devices. Here's what it says specifically about left turns from a one-way street: "The driver of a vehicle on a one-way street that intersects another one-way street on which traffic moves to the left shall stop in obedience to a steady red signal, but may then make a left turn into the one-way street, but shall yield the right-of-way to pedestrians and other traffic proceeding as directed by the signal at the intersection, except that municipal and county authorities may prohibit any such left turn as described, which prohibition shall be effective when a sign giving notice thereof is attached to the traffic control signal device at the intersection."
